One Call. One Team. The Whole Auction.
When a family loses a loved one, when a business closes, when a ranch transitions, when a collection needs a new home — what's needed isn't a piece of the process. It's the whole process, handled by people who've done it before, with a paper trail that holds up to attorneys, trustees, banks, and the IRS.
That's what National Auction USA does. We're a full-service auction firm — not a piecemeal vendor. We appraise, catalog, market, run the auction, settle with buyers, coordinate removal, and deliver clean documentation to whoever needs it. Single asset to entire estate. Single day to multi-week campaign. Online, live, hybrid — whatever the property and the situation call for.
The goal is simple. You make one phone call. We take it from there.
What We Sell at Auction
Four core service lines · Each one fully turnkey
Complete Estate Liquidations
From the entire contents of a home to the home itself. Personal property, collectibles, vehicles, equipment, and real estate — handled in one coordinated process with a single point of contact for the family, the attorney, and the trustee.
Probate sales · Trust dispersals · Special Needs Trust real estate · Living estate transitions · Out-of-state coordination
Estates & Personal Property →Inventory, FF&E, Going-Concern Sales
Retail inventory, restaurant equipment, manufacturing tooling, office FF&E, fleet vehicles — whatever the business needs converted to cash, on a timeline that works for the owner, the landlord, or the lender. Documented for tax purposes and post-sale reconciliation.
Retail closures · Restaurant & hospitality FF&E · Manufacturing & industrial · Bank & lender REO disposition · Asset receivership work
Business Liquidation Auctions →Equipment, Livestock, Land Transitions
When a Montana ranching operation is retiring, downsizing, or transitioning to the next generation, the auction method moves equipment, livestock, vehicles, and outbuildings on a defined timeline. We know what Montana ag equipment is worth, who buys it, and how to market it to the right pool of bidders.
Retirement dispersals · Generational transitions · Equipment-only auctions · Ranch real estate · Estate-driven sales
Farm & Ag Equipment Auctions →Single Pieces or Whole Collections
Firearms (FFL on staff), sporting goods, coins, antiques, fine art, vehicles, equipment — single high-value pieces or entire collections. Consignors get a real market for their items through our auction calendar, our national MarkNet Alliance reach, and the Montana Sporting Auction series for firearms and outdoor goods.
Three annual consignment auctions · Montana Sporting Auction (3x/year) · Firearms (FFL on staff) · Coins & antiques · Specialty consignments

See the closed auction →A Full Estate Liquidation on a Moving Deadline
The Belcher family was transitioning out of their longtime Montana home and needed the entire contents of the estate sold, settled, and removed on a fixed timeline tied to the move itself.
